y v r connecting 250 ohms resistor in series when u
cummunicate with BT in bench calibration?
Answer Posted / vikash suthar
It is because the BT only work if the input impedence is in
the range of the 250 to 600 ohms. so to do make it
communicate we can connect not only 250 ohm but from 250 to
600 ohm any resistor can be connected.
I have experience that even if we connect resisatance 100
ohm it works . below it ,BT not work and up to 900 ohm it
works .but the advisable is from 250 to 600ohm.
